Well, ' 07 was the U.S. & only afew went over, JO wasn't one of them. Northern Ireland held it in '08, I can't remember much controversy then but something about single point slings rings a bell! And of course, as I've said South Africa had to change a number of rules for this year, including jackets.
I seem to remember being told that jackets were outlawed in Poland though, but I wasn't there.
